Why Are Rawhides Bad For Dogs is a common question among pet owners, and understanding the potential risks is crucial for your dog’s well-being. At WHY.EDU.VN, we delve into the safety, digestibility, and ingredients of rawhide chews to provide you with comprehensive information so you can make informed decisions. Discover safer alternatives and expert advice on dog chews to ensure your furry friend’s health and happiness.
1. Understanding Rawhide and Dog Chewing Habits
The safety of rawhide for dogs is a multifaceted issue influenced by several factors, most importantly a dog’s chewing style. A dog’s breed, size, and age dictate how safely they can enjoy chewing on rawhide. It is always best to be informed, observe, and consult your veterinarian for all questions and concerns.
1.1. How Chewing Style Affects Rawhide Safety
A dog’s size is a significant factor. A small Chihuahua cannot generate as much force as a Rottweiler. Moreover, puppies tend to chew less intensely than adults, and senior dogs may have weakened chewing abilities. Because of this, it is important to always observe your dog and be aware that their chewing style may change as they age.
1.2. Rawhide: A Long-Lasting Chew
Rawhides are meant to be long-lasting chews that break down into tiny, soft pieces over time. However, aggressive chewers might be able to break off larger chunks that can cause choking or intestinal blockage if swallowed.
- Offer appropriately sized rawhide to avoid choking hazards.
- Monitor enthusiastic chewers closely when giving them rawhide chews.
- Remove the rawhide chew if your dog breaks off large chunks easily.
- Dispose of the chew in a place where the dog cannot access it.
1.3. When Rawhide Is Safe
For dogs that are gentle chewers, rawhides are generally considered safe as they do not easily break them down into chunks. It’s important to supervise your dog while they enjoy a rawhide and remove it if they’re breaking it down too fast.
2. Examining Rawhide Ingredient Safety
Many dog owners are now concerned about the ingredients in their dogs’ food and treats. Some rawhide chew manufacturers promote their “natural, digestible chews.” This indicates that rawhide chews are not all the same. Rawhide chews are made from dried animal skins, which seems natural enough. What is important to consider is where these rawhide chews are made.
2.1. The Importance of Sourcing
Rawhides made in the United States might be harder to find and more expensive than average rawhide chews, but the benefits are often worth the cost.
2.2. Manufacturing Process
Rawhide chews are made from the leather industry’s leftovers. Most hides are taken directly from the kill floors at slaughterhouses and placed into high-salt brines to slow decay. Most rawhide chews are manufactured in China, and it can take weeks to months before these brined hides make it to tanneries for final manufacturing.
2.3. Chemical Treatments
Once the hide arrives at a tannery, it is soaked and treated with lime to separate fat from the skin. Hair is removed by chemical and physical efforts, and the hide is rinsed again. Salt brines cannot prevent decay, no matter how long they delay it. It is best to fully rinse a rawhide in water prior to giving it to your dog.
3. Rawhide Digestibility: What You Need To Know
Rawhide digestibility can vary from dog to dog and chew to chew. Generally speaking, rawhides are not easily digested. This is why large chunks that break off and are swallowed whole can cause intestinal obstructions in dogs.
3.1. Potential Digestive Issues
Any rawhide pieces your dog breaks off and swallows will have to pass through their digestive system in chunks since they won’t be digested as well as the rest of their food.
3.2. Preventing Complications
It is best to throw away pieces of chewed-up rawhide before your dog has a chance to swallow them, as the chunks have the potential to cause swallowing or intestinal obstructions. Furthermore, if they do swallow a piece that isn’t large enough to cause an emergency issue, the not-so-easily digested rawhide can still hang out for months in your dog’s stomach, leading to gastrointestinal issues or discomfort.
3.3. When Rawhide Is Digestible
That said, dogs that truly take their time chewing on rawhides and don’t swallow large pieces should have no digestive problems with rawhide. Some manufacturers even make rawhide chews out of more digestible ingredients, and although they don’t always last as long as natural rawhides, they are excellent alternatives for dogs that might have stomach or safety concerns with rawhide.
3.4. Rawhide Alternatives
There are also rawhide alternative treats that are similar in texture and look to traditional rawhide but are formulated to be more digestible.
4. Making an Informed Decision About Rawhide
The decision about whether to offer rawhide chews is going to be yours and yours alone.
4.1. Factors to Consider
- Consider your dog’s individual chewing habits.
- Note any health issues.
- Decide if you’re willing to accept the extra expense of high-quality, American-made chews.
- Consult with your veterinarian.
- Read the rawhide label carefully, and remember that the thicker the rawhide, the better. It will take longer for your dog to chew.
4.2. Safe Rawhide Practices
- Supervision: Always supervise your dog while they are chewing on rawhide to ensure they are not swallowing large pieces.
- Proper Sizing: Choose rawhide chews that are appropriately sized for your dog to prevent choking hazards.
